Aerodynamic configuration design is a crucial technology for air-breathing hypersonic vehicles, significantly influencing their flight quality. This paper presents preliminary exploration of novel dual-inlet aerodynamic to broaden the perspectives and achieve superior overall performance vehicles. First, method double-sided intake developed, incorporating characteristics, streamline-tracing technique, multi-segment leading edge method. Using this method, an integrated with that includes ventral dorsal subsequently designed. Second, utilizing in-house graphics processing unit-accelerated computational fluid dynamics code, flow characteristics in isolator are analyzed. Third, performance, longitudinal static stability, inlet compression capability, thrust-drag balance, wide-range assessed, alongside comparative analysis conventional configurations. The study reveals newly designed exhibits intermediate between configurations, while surpassing both terms balance. However, its not ideal. research provides fresh perspective on
